.......the three 2TB drives in RAID 5 is what I was thinking of, and I especially like the hot swap PSU's. Definitely a peace of mind if one fails.
I think the terms were "hot swap internal hard drives"......and "dual power supplies", which I'd think both supplies would still be solid mount to the chassis - to help with earth etc.
You'd be wrong.
You can hot swap the PSU's. They're mounted on slide rails. I tested it and you can indeed disconnect either power cord and the system stays running. You then push down on a small lever and pull the "dead" PSU right out the back of the server.
Enterprise servers aren't built like DIY systems. They're designed with 24/7 operation in mind. Datacenters today often have multiple virtual machines running on one server, so the impact of having a single server offline can affect a large number of customers. The Dell T310 referenced above also has dual NIC's with automatic failover in the event that one fails. At the enterprise level you'll also find cool stuff like the ability to even hot swap cards in PCI slots. Uptime is king inside a data center.
